Free Online Whiteboard: Sketch Diagrams and Export to PDF

PDFly guide · Updated October 2026

Sometimes you just need to draw a box and an arrow. A full design tool is too much, and a pen and paper cannot be shared. PDFly's Whiteboard is an endless canvas in your browser for quick diagrams, flowcharts and notes, with a friendly hand-drawn look.

What you can draw

• Shapes: rectangle, diamond and ellipse, with colour fills, dashed or dotted lines and round or sharp edges.
• Arrows and lines: hold Shift to snap them to neat angles.
• Freehand: sketch with a mouse, finger or pen.
• Text: double-click anywhere, in English or Arabic. Arabic is written right to left.
• Images: insert, paste or drag a picture onto the canvas.

Getting around quickly

Single-key shortcuts select the tools: V select, R rectangle, D diamond, O ellipse, A arrow, L line, P draw, T text, E eraser and K laser pointer. Use Ctrl+Z to undo, Ctrl+D to duplicate and the mouse wheel with Ctrl to zoom. Hold Space and drag to move around.

Present with the laser pointer

Press K, hold the mouse down and move. A red trail follows your pointer and fades after a second. It never becomes part of the drawing, so it is perfect for pointing at parts of a diagram during a call or a lesson.

Save and share your work

• Your board is saved automatically on your device, so it is there when you return.
• Use Export PNG for a picture, transparent PNG for slides or documents, or Export PDF to send a diagram as a document.
• Select some shapes first to export only those.
• Save to file keeps an editable copy you can open later or on another device.

Private by design

Nothing is uploaded. The drawing lives in your browser, and there is no account. On a shared computer, use Clear canvas when you finish.
